Essential Info

INSTEON SwitchLinc 3-Way Dimmer Kit
If you want to control a light from two existing switch locations but don't currently have it wired for a 3-way, this kit is for you. It includes two pre-linked SwitchLinc Dimmers that once installed, can "talk" to each other regardless of where they are installed in the home. In addition the dimmers include LED indicators that let you easily see whether the light is On, Off or at a specific dim level.

Dim the Same Light from Either Switch
A convenient feature of the INSTEON SwitchLinc 3-Way Dimmer Kit is that you will be able to control the brightness level of the controlled light from either dimmer, a feature not found in many traditional 3-way dimmers. Each dimmer also shows the light's current brightness level through each switch's LED indicator bar. This is helpful when one of the dimmers is not in the same room as the controlled light.

The INSTEON SwitchLinc 3-Way Dimmer Kit replaces your existing mechanical wall switches with INSTEON-compatible wall dimmers. These dimmers install easily, attaching to the same wires that your existing wall switches used with the addition of the neutral wire (see how to check if I have neutral wires?). You won't need an electrician come out to install complicated wiring in order to create multi-way circuits. Both dimmers will be able to control the same light. Wall plates are sold separately.

All INSTEON-compatible devices (such as the dimmers in this kit) can be controlled remotely by any number of INSTEON controllers including keypads, home theater remotes or even from your smartphone.

  • More Info

    One of the advantages of having INSTEON SwitchLinc Dimmers is that you can link other INSTEON devices to control the wall switch dimmers remotely. How many times have you jumped into bed and forgotten to turn the hallway lights off? You now have the convenience of linking a bedside controller to turn off your hallway light after you get into bed.

    Lighting Types
    The dimmers are rated for up to 600 watts. If a larger load is needed, a INSTEON SwitchLinc Dimmer (High Wattage) is available. If you have multiple dimmers in the same wall box, the 1000-watt unit may help with keeping the required minimum wattage rating. For info about de-rating, see the spec chart below for the heading: "Mounting." This dimmer switch can control incandescent bulbs, low-voltage halogen (e.g. track), and other low-voltage lights with magnetic or dimmable electronic transformers. If you need to control a fluorescent light fixture or a non-dimmable appliance, try the INSTEON SwitchLinc Relay (Non-Dimming) instead.

    Network Reliability
    To ensure network reliability 2 INSTEON Access Points are suggested in each home with INSTEON-compatible products. While a single Access Point will bridge INSTEON signals between radio frequency and powerline signals, two properly installed Access Points will also act as powerline signal repeaters, maximizing the reliability of your INSTEON network.

    Certifications and Warranty
    All INSTEON SwitchLinc products are safety approved. The factory for SmartLabs Design Products is ISO9001 certified. In order to meet the ISO 9001 standards, the entire factory underwent rigorous inspections of procedures and policies before being certified. The certification received was based on its dedication to high-quality management systems and strict adherence of quality control systems and guidelines. Because of this, SmartLabs stands behind the entire INSTEON SwitchLinc line of products with a full 2-year warranty.

    JOSEPH -- portland, OR   1/3/2012
    Works as expected. More reliable that the X10 it replaced.
    PETER -- cary, NC   1/2/2012
    Easy way to expand a three way to a four way.
    ESTHER -- beverly hills, CA   9/11/2011
    We love our insteon system! It's so easy to control all of our lighting from one laptop screen.
    MARK -- honolulu, HI   3/22/2011
    Easy to install and program the lighting controls
    RICK -- azilda, ON   3/19/2011
    Easy to install and works just like an ordinary three way with more features
    JOHN R -- keystone heights, FL   1/7/2011
    The three-way dimmer switch looks good works very well, just as described, but was expensive for a light dimmer.
    DANIEL -- les cedres, QC   1/3/2011
    They work as expected. Very slick product, much better than the old X10 switches I had years ago. I will eventually fill the house with those SwitchLincs but a few at a time since the cost would be prohibitive in 1 purchase.
    PAUL -- moreno valley, CA   2/27/2010
    Nice that they came pre-programmed to work as a pair. Not too difficult to install but bit harder than a normal switch. Pay attention to the instructions as they wire without the traveler wire between them used.
    VERLIN C -- south beloit, IL   1/4/2010
    I'm converting my house from X-10 to Insteon. The SwitchLinc 3Way Dimmer was one of the last items I had to install. Wiring was easy and linking to my SmartLinc worked fine. Being a 3Way it was a little more complicated, but went well by following your directions. Worked the first time it was turned on.
    MICHAEL -- statesville, NC   12/28/2009
    Great product. easy to install. Sometimes LED on remote is not accurate but for the most part works well.
    STEVEN -- middletown, MD   12/19/2009
    Very good product, wiring diagram not as detailed as it should be (the single red wire labeled LOAD goes to the LOAD, and the red wire labeled LOAD running with the HOT wire goes to LINE).
    MARK -- minnetonka, MN   12/17/2009
    Works just perfectly. I'm no electrician, but I was able to follow the directions and set this up.
    FORREST -- commerce city, CO   12/7/2009
    Throw out what you think you know about wiring. Its easy but in my case I hired a a guy to help out.
    ROB -- hillsboro, OR   9/1/2009
    Works great
    JACQUES -- lasalle, QC   6/8/2009
    Just a pair of Dimmer pre-configured. I finally changed my mind and use them as 2 independant dimmer after removing their links.
    JASON -- rogers, AR   5/14/2009
    These are great! Very easy to install and configure to work with my software.
    RICHARD -- laguna niguel, CA   2/13/2009
    Easy to use after getting accustomed to the dimmer feature.
    ERIC -- merrimack, NH   2/2/2009
    awesome.. installed in minutes and replaced my old toggle link switches
    ARUP -- san jose, CA   12/3/2008
    Works reasonably well. I'm surprised you must have the wireless phase couplers to get the slave to work reliably though.
    CYNTHIA -- richardson, TX   11/26/2008
    Was easy to install and is working well.
